Panelettes

If you choose either of the two versions of the SC-2345 with

configurable connectors or the SC-2350 as your carrier, then you can

install connectivity and interface panelettes to customize your SCC

system. Panelette options (see Table 1, Figure 4) include BNC, SMB,

LEMO (B-Series), MIL-Spec, banana jack, thermocouple plug, 9-pin

D-Sub connectors, rocker switches, toggle switches, momentary

switches, potentiometers, and LEDs. Please note, some panelettes

occupy more than one panelette slot. All panelettes except for the

strain-relief options include lead wires that you connect to the screw

terminals of any SCC module or to the 42-pin screw terminal block

inside the SC-2345 or SC-2350. The thermocouple and

minithermocouple jack connector wires are made of the appropriate

metals to avoid forming unwanted cold junctions.

Screw Terminals

Each SC-2345 and SC-2350 shielded carrier includes a 42-position

screw terminal block for easy access to digital lines of the E Series or

Basic Multifunction DAQ device, including DIO<3, 5, 6, 7>,

PFI<0..9>, GPCTR 0,1, +5V, DGND, AISENSE, FREQ_OUT,

EXTSTROBE, and SCANCLK.

Accessories

The SC-2345 with configurable connectors and SC-2350 offer two

optional accessories. For 19 in. rack systems, choose the rack-mount kit.

If you are using two SCC systems, or a single SCC system with a DAQPad

device, choose the stacking kit to mechanically attach both systems.

Power Options

SC-2345 and SC-2350 carriers have three power options:

• SCC-PWR01 – 5 VDC from the DAQ device or an external supply

• SCC-PWR02 – universal AC external supply

• SCC-PWR03 – 7 to 42 VDC external supply module (power

supply not included)

One power module is included with your carrier. Power modules

are sold separately in case you want to use your SC-2345 or SC-2350

in two or more configurations.

If you choose the SCC-PWR01, it is possible to power your SCC system

with the internal power source of your DAQ device. NI DAQCards and

DAQPads provide 800 mW of total power (480 mW of analog power)

from their internal source. NI PCI and PXI devices provide 4.50 W of total

power (1.74 W of analog power) from their internal source. If the power

draw from your SCC modules is greater than the power available from

your DAQ device, then you must use an external power source. The

SCC-PWR02 includes an AC transformer. However, you must purchase

an additional power cord to match your country’s power requirements.

The SCC-PWR03 does not include a transformer but can be used

with an external transformer that provides 7 to 42 VDC. To

determine the valid power options for the modules in your SCC DAQ

Cabling

You connect your SC-2345 or SC-2350 to your DAQ device using

standard cables. To determine the cabling needed for your

configuration, see Table 2.
